form to variable requirements during the period of use and provided withdouble-cutting edges to sever the usual membrane or skin from the whiteof the egg, this in a reliable and expeditious manner. v

In carrying out the principles of the invention, we `have evolved andproduced, as a pioneer in this line of endeavor, a device implemented byrequisite features to render same aptly useful in removing egg shellsadvantageously and in a manner to assure a clean job when the shellingstep has been completed.

Of outstanding importance, in carrying out the principles of theinvention, is the ever-elfective and easy-to-handle blade, thisstainless steel of proper length and curvature, and provided at its freeend with a penetrating point, along longitudinal edges, with properlyfeathered cutting edges and having proper crosssectional shapes to solvethe problems and over.

come such conditions as are met.

Other objects, features and advantages of the invention will become morereadily apparent from the following description and the drawings.

In the drawings, wherein like numerals are employed to designate likeparts throughout the views:

Figure 1 is an edge elevational view of a socalled egg shellerconstructed in accordance with the principles of the instant invention,showing the manner in which it is employed to accomplish the task.

Figure 2 is a side elevational view observing one face or side of theimplement.

Figure 3 is a fragmentary longitudinal sectional View taken centrally onthe plane of the line 3P-3 of Figure 2.

Figures 4 and 5 are sections taken transversely on the lines 4--4 and5-5 of Figure 2.

The preferred embodiment of the invention as depicted in theaforementioned figures is characterized essentially by two main parts;namely, handle means 6 and blade means 1. The handle suitable for use inremovbeing of thin gage,

may be of a form other than that illustrated but is preferablyconstructed as shown, that is, formed from strap metal of appropriaterigidity, the strap of metal being bent upon itself, as at 8, and thelimbs 9 being ybrought together and riveted, as at the points l0. Therivets l0 serve to secure the shank portion Il securely in place. Theterminals of the limbs 9 are slightly widened, as at l2, to form a sortof enlarged head. This head may be used somewhat in the nature of ahammer, if desired, for cracking the butt end of the shell of ahard-boiled egg to puncture same and to provide for insertion and use ofthe blade means 1. Incidentally, the head -portion l2 is slightly offsetby bending, as at i3, in order to give the blade means an adaptable andappropriate position in relation to the axis of the handle.

Referring now to the blade means, it will be seen that this comprises alength of properly gaged stainless steel, the inner end portion I4 beingsubstantially wide and the remainder of the bladebeing graduallydecreased in width to provide the desired taper.` Looking at the edge ofthe blade, that is, toward either edge, it will Ibe seen that said bladeis bowed longitudinally. The inherent resiliency of the metal is such asto give the blade a preformed curvature comparable, as it were, with thelongitudinal curvature of the outer bulbous surface of the egg shell. Wedesire to stress the fact that the said blade is highly pliant and isthus possessed cf adequate fiexure properties to render it adaptable inconforming to the parts of the egg with which the blade coacts.

The cross-sectional shaping of the blade at different points is also afactor worthy of note. That is to say, the intermediate bend of thecurvature blade is of the cross-section seen in Figure 4. Hence,onesurface or face of the blade is substantially flat across, as at I5,while the opposite surface is convexed, as at I6. The longitudinal edgesare featheredged to provide :cutting edges I1. Through the rounded tipor penetration point I8, the metal of said blade is double convexed,that is, convexed on both sides, as at the points I9 and 20.

Reviewing the construction :and description thereof, the followingrelevant factors will be full well appreciated to-wit:

The resultful purpose of the device disclosed is to facilitate, whenproperly used and handled, the removal of the shell of a hard-boiledegg.

Upon examination of the details of construction, it will be noted thatthe device, as described, consists of a very thin blade (.015approximately) tapering from base to point slightly in thickness.prising a handle provided at one end with a It is curved to approximateconformity of an longitudinally bowed highly exible stainless averageegg.
